Because the Tobii EyeX is an eye tracking advice, the design team wanted to ensure that every game mechanic created in The Channeler would be centered around the eye. Learning about the eye was key. The eye does not move smoothly, but instead jumps from place to place rapidly. Things must happen swiftly and suddenly in order to create challenges. Eye strain can also be an issue. So we must ensure that the eye is not overstimulated for too long. These are just a couple of the relevant challenges in our design process.
